99517-93-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 99517-93-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,5,1 and 7 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 99517-93:
(7*9)+(6*9)+(5*5)+(4*1)+(3*7)+(2*9)+(1*3)=188
188 % 10 = 8
So 99517-93-8 is a valid CAS Registry Number.
